That sounds like you've run into a video mode bug.  If you're using an nVidia 
videocard, and the Nouveau driver (used by default) doesn't work for you, you 
can blacklist it by adding the following line to 
/etc/modprobe.d/blacklist.conf:

   blacklist nouveau

Besides the above, examine the contents of /etc/X11/xorg.conf to find out what 
video driver is used for X.
